Archean gold deposits are the most important source of gold in Canada. While mining of gold deposits in the Abitibi subprovince is well underway, the neighbouring Wawa subprovince is relatively underexplored, but this region has a similar potential for hosting world-class gold deposits. The paucity of regional gold mineralization models that can be used to target exploration drilling has hindered exploration in the Wawa subprovince. The Michipicoten greenstone belt in the Wawa subprovince represents a natural laboratory to use existing gold deposits to develop regional models of gold deposits that can be applied across this subprovince and to orogenic gold deposits worldwide. The main objectives of this multidisciplinary research program are to: (1) determine the structural setting and control on gold mineralization at the Island Gold deposit, (2) evaluate the nature and extent of alteration associated with mineralization as well as characterize the protoliths that host mineralization at the Island Gold mine, and (3) quantify the change in metamorphic grade from the Michipicoten Greenstone belt (hosting the Island Gold Mine) across the Wawa gneiss domain to the Kapuskasing uplift to the East. This research program builds on previous studies in the Michipicoten Greenstone belt and will generate an enhanced tectonostratigraphic framework to prioritize exploration at the local and regional scales and test the crustal continuum model for orogenic gold deposits.

大将黄金矿床是加拿大最重要的黄金来源。虽然在阿比蒂比·苏伯（Abitibi Subprovince）的黄金沉积物开采良好，但邻近的瓦瓦（Wawa Subprovince）相对不受欢迎，但该地区具有与世界一流的金矿矿床相似的潜力。可用于靶向勘探钻探的区域金矿化模型的匮乏阻碍了Wawa Subprovince的勘探。 Wawa Subprovince的Michipicoten Greenstone带代表了一个天然实验室，使用现有的黄金沉积物来开发可在该subprovince和全球造型金矿上应用的金矿区域模型。 The main objectives of this multidisciplinary research program are to: (1) determine the structural setting and control on gold mineralization at the Island Gold deposit, (2) evaluate the nature and extent of alteration associated with mineralization as well as characterize the protoliths that host mineralization at the Island Gold mine, and (3) quantify the change in metamorphic grade from the Michipicoten Greenstone belt (hosting the Island Gold Mine) across the Wawa gneiss domain向东方的Kapuskas uplift。该研究计划以先前在Michipicoten Greenstone Belt的研究为基础，并将产生增强的构造构造学框架，以优先在局部和区域尺度上进行探索，并测试造基因金矿的地壳连续性模型。
